Optimal - Observable Analysis of Possible New Physics Using the b - quark in γγ → tt̄ → bX
We study possible anomalous top-quark couplings generated by SU(2)× U(1) gauge-invariant dimension-6 effective operators, using the final b-quark momentum distribution in γγ → tt̄ → bX. Taking into account non-standard tt̄γ, tbW and γγH couplings, we perform an optimal-observable analysis in order to estimate the precision for the determination of all relevant non-standard couplings.

متن کاملEmergence of Time and Observable Physics
A new idea, which is deeply rooted in noncommutative geometry, is proposed in this paper to connect general relativity, quantum theory thermodynamics, cosmology and the foundation of quantum mechanics. The emergence of time and the arrow of time become natural in the new scheme. 1. the issue of time An important question is asked explicitly in some literatures such as [2], which concerns with t...
متن کاملObservable Optimal State Points of Subadditive Potentials
For a sequence of subadditive potentials, a method of choosing state points with negative growth rates for an ergodic dynamical system was given in [5]. This paper first generalizes this result to the non-ergodic dynamics, and then proves that under some mild additional hypothesis, one can choose points with negative growth rates from a positive Lebesgue measure set, even if the system does not...
متن کاملSPECULATIONS CONCERNING POSSIBLE NEW PHYSICS FROM EXPERIMENTS ABOVE 10 TeV
(B) Other. There are a number of possible new kinds of effects. Of course, one could speculate without constraint, but today one has aVailable viable gauge theories of strong, weak, and electromagnetic interactions and it seems preferable to speculate within the context of these new effects. It may be that none of the following speculations will be realistic and we are only free to discuss them...
متن کاملfabrication of new ion sensitive field effect transistors (isfet) based on modification of junction-fet for analysis of hydronium, potassium and hydrazinium ions
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
